Is Eucalyptus Oil Safe for Dogs?
Why it’s a problem
Eucalyptus oil is rich in eucalyptol, which irritates the gut and depresses the nervous system in dogs. Exposure usually comes from a dog chewing a bottle, licking spillages, or grooming oil off its coat. Small dogs are at higher risk from the same dose.
How to keep your pet safe
Keep bottles sealed and stored away from pets, and never apply eucalyptus oil to a dog or its collar or bedding. If you diffuse it, do so briefly in a large, ventilated room the dog can leave. Choose pet-safe odor control such as regular cleaning instead.
Warning signs to watch for
Drooling, vomiting, diarrhea, weakness, wobbliness, depression, seizures
When to call the vet
Call your veterinarian or a pet poison hotline if your dog has swallowed or contacted eucalyptus oil. Do not induce vomiting unless a professional tells you to.
Common questions
Is eucalyptus oil safe to diffuse around dogs?
Brief passive diffusion in a large, ventilated room is lower risk, but dogs should always be able to walk away. Never diffuse it in a closed room or near a dog with asthma or other breathing problems.
Can I put eucalyptus oil on my dog’s collar for fleas?
No. Concentrated oil on a collar sits against skin all day and can be licked off. Ask your veterinarian about proven flea control instead.
